【问题描述】：

我正在尝试连接到我的 sql server 数据库，但它无法正常工作。

freetds 正在运行，查看命令：

tsql -S myserver.database.windows.net -U myuser -P mypassword

输出：

locale is "C/UTF-8/C/C/C/C"
locale charset is "UTF-8"
using default charset "UTF8"
1>

但是当我尝试运行命令 isql 时，它返回错误。

命令：

isql -v MYSERVER myuser mypassword

输出：

[IM002][unixODBC][Driver Manager]Data source name not found, and no default driver specified
[ISQL]ERROR: Could not SQLConnect

我的文件：

freetds.conf：

#   $Id: freetds.conf,v 1.12 2007-12-25 06:02:36 jklowden Exp $
#
# This file is installed by FreeTDS if no file by the same 
# name is found in the installation directory.

# Global settings are overridden by those in a database
# server specific section

    # Whether to write a TDSDUMP file for diagnostic purposes

    # Command and connection timeouts

    # If you get out-of-memory errors, it may mean that your client

[MYSERVER]
   host = myserver.database.windows.net
   port = 1433
   tds version = 8.0
   client charset = UTF8

odbcinst.ini：

[FreeTDS]

Driver      = /usr/local/lib/libtdsodbc.so
Setup       = /usr/local/lib/libtdsodbc.so
UsageCount  = 1

TraceFile   = /Users/giorgecaique/Documents/sql.log

odbc.ini：

[MYSERVER]
Description = MYSERVER
Driver      = FreeTDS
Database    = mydatabase
Server      = myserver.database.windows.net
UserName    = myuser
Password    = mypassword
TDS_Version = 8.0

谁能帮帮我？我已经看过很多关于如何解决这个问题的教程，但没有一个对我有用。

【解决方案1】：

在odbc.ini 文件中，您需要一个Servername 属性，它指向freetds.conf 中的DSN 名称。此外，8.0 不是有效版本（长篇大论，请参阅文档），它是 UTF-8 而不是 UTF8。例如：

freetds.conf:

[MYSERVER]
   host = myserver.database.windows.net
   port = 1433
   tds version = 7.1
   client charset = UTF-8

然后在odbc.ini:

[MYSERVER]
Description = MYSERVER
Driver      = FreeTDS
Database    = mydatabase
Servername  = MYSERVER
UserName    = myuser
Password    = mypassword
TDS_Version = 7.1

祝你好运！

感谢您的回复，但仍然无法正常工作。 “Could not SQLConnect”错误仍然存在。

【解决方案2】：

您是否检查过您拥有库/usr/local/lib/libtdsodbc.so？

我遇到了类似的错误。我按照link 的本指南修复了我的错误。

我相信您可能没有安装freetds 的驱动程序，您可以通过Homebrew 安装： $ brew install freetds --with-unixodbc

【解决方案3】：

您是否从这里尝试过 emehex 的回答：

Can't open lib 'ODBC Driver 13 for SQL Server'? Sym linking issue?

sudo ln -s /usr/local/etc/odbcinst.ini /etc/odbcinst.ini
sudo ln -s /usr/local/etc/odbc.ini /etc/odbc.ini
